IOCOMOTI'VE FRONT-END STRUCTURE.

Application filed January 10, 1937. Serial ll'o. 160,846.

My' invention relates to railway rollin stock and consists of an improved front en structure for locomotives.

The main object of my invention is to provide a single member adapted to be applied to the front end of the side frames or locomotive bed, said member preferably including other elements of the locomotive such as the cylinder saddle, the cylinders, the front deck plate, the pilot beam, and front truck mount- 111%, elements.

resent locomotive construction results in a shallow depth of.the frame at the front end due to the provisions usually made for bolting the cylinders thereto and for clearing the front truck. Preferably my invention is embodied in a one-piece casting with the parts mentioned formed integrally therewith. B making the c linders and saddle integral wit the casting} eliminate the labor and parts re uired for assembling separate elements arid provide greater strength than can be obtained in the assembled structure.

In the accompanying drawings illustrating my inventionigure 1 is a side elevation of my front end member showing the same applied to the forward end of a locomotive bed or side frame and mounted upon a pony truck.

Figure 2 is a top view of one longitudinal half of the same structure.

Figure 3 is a vertical section through. one transverse half of the locomotive side frame showing the adjacent portion of my front end in elevation. The same is taken on line 3-3 of Figure 2.

Figures 4, 5 and 6 are side elevations of various modifications in the construction 0 my front end member whereby it is adapted to be secured to the locomotive frame in different ways.

In the construction illustrated in Figures 1, 2 and 3, the front driver of the locomotive is indicated at 1 and the side frame of the locomotive is indicated at 2, the same terminating just beyond the pedestal for the front driver and at this portion preferabl having tog and bottom flanges 3 and 4 w ich exten inwardly.

My front end member is shown as a onepiece casting having at its rear end side ieces 5 adapted to be seated between the said arne flanges 3 and 4 and tube bolted to the side frame as indicated atfi. .Transverse elemen and connect the portions of. the end castmg WlllCh are bolted to the side frames 2 and the lower one of these elements includes inteal pocket forming elements 9- for mounting the radius bar 10 of the pony truck, indicated by the wheels 11.

In front of the locomotive side frames 2, the side pleces of the casting have cylinders 12 formed integrally therewith and preferably the steam chambers. such as piston valve chambers 13 or steam chests, are formed integrally with the cylinders. This portion of the casting also includes the boiler saddle 14 and sultable'steam passages 15 leading from the cylinders through the saddle.

In front of the cylinder and saddles the casting forms a front deck late 16 which has an integral truck pivot caring 17 and the deck plate terminates in a pilot beam 18 extending transversely of the frame and in front of the cylinders.

In the structure illustrated in Figure 4, the locomotive frame 20 has n er and lower members 21 and 22 in front 0 t e front driver pedestal and-the front end casting 23 has rearwardl projecting members 24 and 25' ali ed wlth rame elements 21 and 22 andwe ded thereto as indicated at W. It will be-understood that the front end casting includes cylmders 26, saddle 27, steam chambers 28 and guide elements 29 for thefront truck radius rod 30, all similar to the more detailed structure shown in Figures 1 and 2.

In the modification illustrated in Figure 5, the locomotive side frame 31 terminates in front of the front driver pedestal in longitudinal arms 32 and 33 and the rear end of the f front end casting terminates in arms 34 adapted to overlap the side frame arms 32 and 33 and to be bolted thereto as indicated at 35.

In the modification illustrated in Figure 6. the locomotive side frame 36 terminates at the rear of the pedestal of the front driver 37 and the pedestal 38 for this driver forms the rear part of the front end casting, the sameextending to the right of the portion illustrated in the drawing and including the cylinders and other parts referred to in connection with Figures 1 and 2.

In this construction the casting may be welded to the locomotive side frame as indicated at W or the upper and lower ortions of the side frame and end casting etween pedestals 38 and 39 may be overlapped and bolted or riveted together similar to the arrangement shown in Figure 5. In this construction I show a brake cylinder fulcrum bracket 40 formed inte ral with the casting adjacent to the radius bar pocket 41. This element and other desirable elementsmay be advantageously added to the various front end castings described by me.

In each embodiment of my invention, a member forming the front end of the frame has formed integrally therewith one or more other locomotive elements hitherto separately secured to the frame and the construction described herein makes possible the attainment of the objects set forth at the beginning of my specification.

Other modifications in the form of the front end member and in the method of attaching to the locomotive frame may be made without departing from the spirit of my invention' and I contemplate the exclusive use of such modifications as are included in the scope of my claims.

I claim:

1. A locomotive front end member forming a forward extension of and detachable from the locomotive frame and including integral cylinders.

2. A locomotive front end member applicable to the locomotive side frames and forming a forward extension thereof and includilng integral steam cylinders and boiler sad- 3.
